    摘要: Skeletal isomerization of n-alkenes into isoalkenes and enrichment of isoalkenes in alkene-containing hydrocarbon mixtures is effected in the presence of an isomerization catalyst containing a microporous silicon-containing alumophosphate.A goal of the method for skeletal isomerization is to provide a running time in one operating period of over 100 hours. This goal is achieved by using, as isomerization catalysts, microporous alumophosphates with a molecular sieve structure whose pore inlet openings have a diameter of 0.4 to 0.6 nm which are mixed with a binder and activated at temperatures of 623 to 873K.

    摘要: A gage according to the present invention for use in measuring engagement parts of a pneumatic hose coupler and including a body and a spring loaded contact rotatably mounted to the body. The body includes an alignment part for locating the gage on the coupler and a member for contacting one of the engagement parts. The contact is biased into contact with another of the engagement parts and calibrated indicator marks provide a visual indication of the angular distance between the two parts. Sights through the gage measure another angular dimension between coupler engagement parts. The gage also includes a plug part for measuring vertical clearance between other parts of the coupler.
